EmberJS: Get PDF in a new window tab from server using link

I want to use the default behavior of a browser to open a pdf file in a new tab using Ember.
I'm not using Ember-Data and as a server side resource I'm using Python. So I set the proxy address on startup of Ember to point to server side address.

I built a route page and I have a link to open my PDF file in the browser like

<a href="/path/apps/list.pdf?list=current" target="_blank">Open</a>

And the server Python resource returns a pdf:

@get("/list.pdf") 
@params(C.String("list"))
def get_list_pdf(list):   
    //some code to build the pdf string 
    Response(pdf_string, headers={'Content-Type': 'application/pdf'})

I tried it in an application without ember to access the resource from a link and it is fine. But with Ember I'm not able to do that.

I got this error: Uncaught UnrecognizedURLError: /path/apps/list.pdf?list=current ember.debug.js:4914

Any suggestions how I can achieve that?

Solution

As a solution to my problem I created a new route and I added to its template the html object element. I added also a {{link-to 'the route' (query-params url='the url') }} to transit to the route to render the PDF.

The template.hbs

<object data={{url}} type='application/pdf' />
